WINDOW.

Specification of Letters Patent.

Patented July 9, 1918.

Application filed July 25, 1914. Serial No. 853,000.

in the usual manner and may be swung 1n- 'wardly and retained 1n such pos1t1on at any desired horizontal angle. The particular object of this invention is to provide means of ventilation without creating draft and to regulate such ventilation as desired and further, to provide the means of washing both sides of the glass of a window from the inside of the room with a secure manner of construction and operation.

In a window of this type the lower sash can be swung inwardly at any given point of the height of the window frame and I have found it highly desirable to provide means for preventing the upper sash from being swung inwardly until it is lowered to substantially its lowermost position at the sill.

By raising the top part of the lower sash above the head of the window frame and thus providing space for clearance, the upper sash may be swung inwardly when lowered to the sill, and freely handled to facilitate the cleaning of the glass at both I Both sashes are restored to their normal vertical position in the window-frame by simply reversing the operations as described. I am furthermore enabled to provide a simple and efficient system of weather stripping for both sashes, which is a factor of the utmost importance in such win dows.

engagement'when it is desired to swing the sash iniiardly'or to reengage again with the sash when to be swung back into its vertical position. They prevent a tight joint to keep out wind and weather, impair the free travel of the entire sash in the window frame and obstruct the free operation of the sash. Furthermore, the split sash, consisting of jointed members affords greater opportunities than the normal sash for the weather, drafts and-dust to enter, and it therefore materially impairs the window in ts more essential requlrements of protection against the elements.

The objects of my present invention are to improve upon the construction of windowsof'the type herein specified, and obviate the difliculties heretofore encountered in the satisfactory construction and operation of 'such windows.

I am enabled to reduce the number. of parts necessary for eflicient operationof the sashes to a minimum, thus reducing the cost of the construction, and I do not alter the general appearance of an ordinary double hung window, yet at the same time I am enabled to make a thoroughly weather-tight window without constructional difliculties.

In my window, the sash proper is directly and pivotally connected by arms to upper slides, which travel in grooves in the-jamb of the window frame, and these slides are connected to the sash chains. Lower independent slides are also pivotally connected to the lower end of the sash. The arms are adapted to lie in recesses formed in the jamb of the window frame and in the sides of the sash, so that said arms are hidden from view when the sash is in normal closed position, and a better weather tight joint may bev formed.

I have found that the sash is aptto rock sidewise on its lower pivots when swung inwardly, due to the independent movement of the slides at each side and other causes, andone of my improvements consists in providing locking means for the slides for pre venting this rocking action and thereby stabilizing the sash when swung in.

These locking devices are vpreferably automatic in action, and-are preferably applied to the pivotal connections between the upper ends of the arms and the slides.

Those looking devices are also preferably so constructed that the lock'is not brought into operation until the sash is swung inwardly beyond a predetermined angle, so t the sa h m be u g severely a a come locked in the grooves in the jamb. of;

the window frame. By this means the rocking of the sashwhen swung inwardly is 'Referring to the drawings, A represents the jamb at one side of the window frame, the other; side' not being shown, for convenience of illustration, B represents the top ofthe window frame or lintel, C represents avoided, and a firm, ellicient, and practical-the window-sill and D and E indicate the .eonstructionis provided, safe in operation.

Another improvement consists in provid: ing holding means, preferably in conjunction with the pivotal connections of the arms with the; sash, and preferably automatic in action, for holding the sash at any desired n e he ung inwar y T i ha be found to be a very desirable feature, because the sash may thus be swung inwardly and madei to stay in any desired position against wind pressure for purposes of regulating ventilation or to afford the means of washing b'othsides of the glass from the interior of the room.

The invention consists of means for carrying out all the above objects and the invention is illustrated inthe best formknown to me in the accompanying drawings, in

hereinafter pointed; out, which pertain to my lnvent on.

Both the lower sash F and the upper sash LG are adapted to slide vertically-in the usual low and maybe swung'inwardly at any de-' sired vertical position, but in accordance witlrmy invention, the upper sash G which is shown in dotted lines in Fig. is not adapted to be swung inwardly when in its uppermost or raised positiomand in the operation of the window, the upper sash is adapted to be lowered substantially to its 1 lowermost position before it can be swung inwardly. Ordinarily the lower sash F would be swung inwardlyand may then be partly raised above the head of the window frame in such position while at an angle andthen the upper sash G can be loweredv and, swung inwardly. 7' In this way interfcrence between the sashes, for cleaning and ventilating purposes, is obviated. I

' Both sashes as shown move in recesses in the ja nb of the window frame, the recess for the lower sash F being formed bythe rabbet H: and he, l'ecess for the upper sash being fori'ned; by the" rabbet J, it being understood that the construction ofbotlrjalnbs or. the.

window framcis the same, -A stripKgp'refem ly of h avy 01 1; and Pre erab y in t form of an angle, is proyided in; the recess or .rabbet J for, the upper sash G. and 'sa'id sash is providedgwitha longitudinal gl'OOVQL into which fthe. weather strip 7 extends. This weather st-rip K extends vertically through- -out onlytl ejupper half oft-he window frame and terminates at the'point a or slightly be- 'low, as indicated in Fig. 1 ,sothatwhen the upper sh isinits normal raisedposition, it cannot be swung inwardly, butsaid sash .must be lowered to clear the stri; K, in order to permit the sash tov be swunginwardly.

Ehe e ilb ea i nf the was 1 an them pes tien likemann t a theusin pea- 'usual parting bead, serving as a means to hold the sash against wind pressure in its normal position, and also serves as an effective weather strip as specified.

A weather strip O preferably of metal and preferably in the form of a channel is provided in the rabbet H for the lower sash F and said channel, as shown, faces in wardly and cooperates with a similar channeled metallic weather strip P secured to the lower sash F. The weather strip 0 preferably extends substantially throughout the height of the window and in connection with the rabbet H and the cooperating channeled strip P on the sash, forms an efiicient weather-tight joint, by interfitting With the channels 0.

The jambs of the window frame, as shown, are provided with grooves in the pulley stiles back of the edges of the sashes and these grooves may be in the form of metallic tracks Q, preferably having the inwardly extending retaining members or flanges b, as shown in detail in Figs. 10 and 11. Movable upper slides R preferably in the form of blocks or strips of metal are retainedin said grooves or tracks Q, and said upper slides are connected with thesash weights D and E as by means of the usual sash cords or chains 0.

. Arms S are pivoted to. the slides at one end and pivoted to the sash at the other end,

thepivotal connections of these arms S for both the upper and lower sashes being substantially the same, so that the connections of only one set of arms needbe described, and these arms S afford means for raising and lowering the sash verticallyin its regu- V lar'fram'e-guides and for swinging the sash inwardly and holding it in such position.

The bottom of the lower sash F is provided with members cl at each side having a pivotal connection with lower independent slides 6 shown in detail in Fig. 7 which also travel vertically in the grooves f in the amb of the window frame. As shown, in this instance, the slide a is provided with the stud or pivot pin 9 engaging the aperture 71, in the member cl, thereby forming a pivotal connection. The lower slides e slide independently of the upper slides, it being stance provided with the pins is engaging apertures 0 respectively in the lower'slides sliding vertically in the grooves or tracks Q, the detail of this pivotal connection being shown in Fig. 6. Suitable means are provided for maintaining the lower sash F in closed position and as a convenient constructlOIl'I have shown a sprlng latch q secured to the sash, and having tongue 1" which engages the groove f in the window frame. The tongue 1 is retracted from engagement with the groove f when it is desired to swing the lower sash F inwardly.

Suitable means are provided for holding or latching the sashes at any desired angle when swung inwardly and I prefer an automatic'lock arranged in connection with the pivotal connections of the arms S to the sashes. The details of this looking or latching device are shown in Figs. 2, 3, 4t and 5, in which 8 is a socket piece adapted to be set into the side of the sash and provided with a central bolt 25 over which is placed a coiled spring a adapted to be compressed between the bottom of the socket piece 8 and a hold ing member 1), held in the socket piece and preferably provided .as shown with the radial teeth to. Another holding member or clutch member as is held beneath the head g of the bolt and is provided on its face with teeth or grooves cooperating with the teeth to of the member 42. The member an is adapt ed. to be rotated on the bolt and the arm S is adapted to be rigidly connected to the member 00 as by means of the pins 2. The screw 5 passing through the arm S and screwed into an interiorly screw threaded socket 6, in the bolt 25, holds the arm'S and locking members together, so that as the sash is moved inwardly and outwardly, the toothed holding member 8 turns on the looking member 2) and the cooperating teeth hold or. latch the pivotal connection in any desired position.

slides and other causes I provide means in connection with the pivotal connection of the arms S with the upper slides, for locking the upper slides to the grooves or tracks and I prefer that this locking of the slides should not be brought into operation until the sash has been swung inwardly beyond a certain predetermined angle, because it is desirable that the sash should be free to slide vertically after it has been swung inwardly to a certain degree.

This automatic locking arrangement for the upper slides is illustrated in detail in Figs, 10, 11, 12 and 13 and as shown each upper slide is provided with a stud or pin 7 preferably having a squared shank 8, a round throat and an oval beveled head 10. A plate 11 is loosely arranged on the squared shank 8' and is provided with a suitable hook 12 or other engaging means for the pulley chain 0. The arm S is provided witha round aperture 13 in its'end cooperating with a round throat 9 and the edge of the aperture 13 is beveled at 14: preferably at a slightly difl'erent angle from the bevel of the head 10, so that as the sash is swung inwardly and the arms S rotate on the pivots 9, the plates 11 are squeezed or forced against the tracks Q and lock the slides. There is, however, suffi- T cientplay in the pivotal connections of the arms S as described, to permit the sash to be swung inwardly to a given angle of about 15 degrees more or less before the locking of the slides takes place and beyond this angle the slides become more firmly locked in position, so that rocking of the sash cannottake place. The rocking is further prevented by the lockingcon eotions of the arms S with the sash and a very firm and rigid construction is provided, which has been found to operate efficiently and well in actual practice.
